Hey there, I totally get your concern about your hair still being thin after a year post-transplant. In my experience, it's common for results to take time to fully show up. After my own transplant, it took about 18 months for my hair to fully grow in and thicken up.
It's good to stay patient and keep in touch with your transplant surgeon for regular check-ups. My transplant cost about $5000, and I had it done in a clinic in Istanbul. Hang in there and give it a bit more time before jumping to conclusions about whether it was a success or not. In the meantime, focus on taking good care of your scalp and following any post-op instructions from your surgeon.
